hi gays:

 

   I want  to use the  eval-adv7280MEBZ  as the client,and rk3288 as the master . as now,the power supply of the eval-adv7280MEBZ  board is ok,i just connetct the i2c-clk pin and i2c-data pin  to the rk3288,the gpio-rest-pin、gpio-power-pin leave it alone.  but after i done it,  the i2c is not work.yeah,the i2c  addres  has set to 0x42 . i not sure wether i need to config the gpio-rest-pin、gpio-power-pin on the eval-adv7280MEBZ to let the i2c work.
